188 CURCULIOlSriD^E. 



[LeConte 



prothorax, humeri prominent, oblique and rounded, sides nearly parallel, 

 then oblique, tips rather broadly rounded, posterior callus small, very 

 prominent ; striee fine, interspaces nearly flat. Antennae and legs brown, 

 tarsi long. Length 1.8 mm. ; .07 inch. 



Capron, Florida ; Hubbard and Schwarz ; one specimen. 



The black band extends forwards to beyond the middle on the third, 

 fourth and fifth interspaces, and is prolonged backwards on the fifth and 

 sixth, as far as the callus. 



12. B. bituberosus, n. sp. 



Black, covered with dirt-colored scales. Beak stout, shorter than the 

 prothorax, which is of the same form as in the preceding, feebly channeled 

 and more finely granulate. Elytra wider than the prothorax, humeri less 

 oblique, obtusely angulated, prominent; striae deep, interspaces convex, fifth 

 more elevated behind, and terminating in a large tuberosity ; the third is 

 a little wider and more convex than the adjoining ones. Antenna, tibire 

 and tarsi dark testaceous ; third joint not dilated, fourth as long as the two 

 preceding united. Length 3mm.; .12 inch. 



One specimen, Kansas ; and one from Florida. 



13. B. transversus, n. sp. 



Robust, less convex, black, covered with blackish-gray scales. Beak 

 stout, curved, as long as the prothorax, naked, punctulate, sub-carinate 

 near the base, lateral grooves deep; frontal fovea large. Prothorax nearly 

 one-half wider than long, sides sinuate, very strongly constricted in front, 

 very finely granulate. Elytra uneven, marked with vague impressions, one- 

 half wider than the prothorax, humeri prominent, slightly rounded, posterior 

 callus large, obtuse ; striae fine, interspaces feebly convex. Antennae and 

 legs nearly black, tarsi moderately long. Length 2.3 mm.; .15 inch. 



Detroit, one specimen; Hubbard and Schwarz. Remarkable for the form 

 of the prothorax, by which an excellent transition to the next genus 

 Pnigodes is established. 



PNIGODES n. g. 



This new genus is closely related to Bagous, and has the prosternum 

 similarly excavated. There is also no difference in the beak, which is stout 

 and curved, nor in the antennae, which have the funicle 7-jointed; the 

 first joint is stouter and the second longer than the others, which increase 

 gradually in thickness, and the club is pubescent and annulated. The legs 

 are stouter than in Bagous, the tibiae sinuate on the inner side, hooked at 

 tip ; the tarsi rather short, joints 1-3 equal, fourth nearly as long as the 

 others united, claws divergent. 



The form of body is, however, remarkable. The prothorax is wider 

 than long, narrowed behind, widely lobed on the sides before the middle, 

 then suddenly and very strongly constricted and tubulate. The elytra are 

 wider than the prothorax, with the alternate interspaces elevated, and a 

 callus at the hind extremity of the fifth; the humeri are very prominent 

 and rounded, not aiigulated.
